Petunia plant named Cas 56

ABSTRACT

A new and distinct cultivar of petunia plant named Cas 56, characterized by the combined features of medium to large white flowers, light throat with dark violet veins, vigorous, bushy growth habit, semi-erect to overhanging plant habit, and light to medium green foliage.

The present invention comprises a new and distinct cultivar of petunia, hereinafter referred to by the cultivar name Cas 56.

Cas 56 was originated from a hybridization made by the inventor Gabriel Danziger in a controlled breeding program in Moshav Mishmar Hashiva, Israel in 1992. The female parent was a seedling designated X 31. The male parent of Cas 56 was a seedling designated Y 43. Both parents are proprietary cultivars used in the breeding program.

Cas 56 was discovered and selected as one flowering plant within the progeny of the stated cross by Gabriel Danziger in 1992 in a controlled environment in Moshav Mishmar Hashiva, Israel.

The first act of asexual reproduction of Cas 56 was accomplished when vegetative cuttings were taken from the initial selection in December 1992 in a controlled environment in Moshav Mishmar Hashiva, Israel, by, or under the supervision of, Gabriel Danziger.

Horticultural examination of selected units initiated in December 1992 and continuing thereafter has demonstrated that the combination of characteristics are herein disclosed for Cas 56 are firmly fixed and are retained through successive generations of asexual reproduction.

Cas 56 has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length without, however, any variations in genotype.

The following observations, measurements, and comparisons describe plants grown in Hillscheid, Germany, under greenhouse conditions which approximate those generally used in commercial practice.

The following traits have been repeatedly observed and are determined to be basic characteristics of Cas 56, which in combination distinguish this petunia as a new and distinct cultivar:

1. Medium to large white flowers.

2. Light throat with dark violet veins.

3. Vigorous, bushy growth habit, with branches fully extending in all directions from center of plant.

4. Plant habit semi-erect in the beginning, hanging as the plant matures.

5. Light to medium green foliage.

The accompanying photographic drawings show typical flower and foliage characteristics of Cas 56, with colors being as true as possible with illustration of this type. The photograph on Sheet 1 illustrates Cas 56 cultivated in a hanging basket. The photo on Sheet 2 comprises an enlarged showing of single flowers of the new cultivar.

In the following description, color references are made to The Royal Horticultural Society Color Chart. The color values were determined indoors in August. Flowers were taken from plants cultivated in hanging baskets in an open greenhouse in Hillscheid, Germany. For the description, the upper parts of the plants were observed or measured.
